When they release the Mistlands update, the game will still be around, so how is that not living? Will you like the game less when you come back to it in a few month? From my experience, you might find that you like it more after some time off.

It's a natural tendency to want everything now, but sometimes you have to have patience. Find something else to take up your time for a while. Maybe it will be a happy Christmas of Valheim!

BTW, There are currently 5 biomes. The Mistland update will add 1 to that. I predict that, within a few days (maybe less) there will be people rushing through it who are disappointed that there isn't more.
